functioning of the engine. The advantages of the present invention are readily ap parent from a consideration of the follow-. ing description taken in conjunction with the annexed drawings- For convenience, the

term oil is used herein as descriptive of lubricants having the same general characteristics and purposes.

Fig. 1 is a diagrammatic view of an arrangement of an internal combustion engine and oil radiator, the same constituting an embodiment of my invention. Fig. 2 is an enlarged view of the oil radiator of Fig. 1 and Fig. '3 discloses certain conducting tubes of the oil radiator.

In the drawings, Fig. 1 illustrates an internal combustion engine 1 with water radiator 2 and airplane propeller 3, oil radiator 4 having conections with the engine and water radiator as hereinafter described. Oil

- upper part to the lower part of lower compartment 5, inlet oil line leading therefrom to engine 1. Upper compartment-6 serves as an oil reservoir with oil feeding through opening 8 as required, vent 11 allowing free air to escape to atmosphere. Uil outlet line 10 leads from engine 1 to upper part of lower compartment 5.

The engine is water cooled, heated water from the engine during its normal operation passing by water line 12 through three-way valve 13 to water radiator 2, thence by line 12 around tubes 9 of oil radiator 4. to engine 1. During starting and While warming up the engine preliminary to operation under load, three-way valve 13 is turned so that heated water from engine 1 passes by line 12 to line 12 and thence around tubes 9 of oil radiator 4 to engine 1.

In operation, the engine is started and three-way valve is closed so that water from the engine does not circulate through water radiator 2 but instead passes by line 12 around tubes 9 of oil radiator 4: and thence back to engine. The function of baflie 7 is to separate the oil in circulation from the oil in the reservoir so that a relatively small quantity of Oil will be rapidly circulated through the radiator in order that the engine may receive warm oil as quickly'as possible after starting. The oil in the reservoir compartment will eventually become heated by conduction but it is not necessary or desirable that this oil become heated as quickly as the oil in lower compartment 5.

The water speedily becomes heated and as it passes around oil conducting tubes '9, the,

oil in such tubes as well as the remaining oil in the oil radiator, by conduction, is heated. The same oil may thus be used repeatedly, so facilitating rapid heating. lVhen this heating has continued for the desired time, three-way valve 13 is turned so that water will circulate through the cooling radiator 2 and thence by line 12 around tubes 9 and back to engine.- During operation under full load, the water in the line 12 may be coolerthan the oil passing through the engine so that the water passing through oil radiator 4. will tend to cool the oil and maintain the same at a-proper'temperature. Entrained airmay pass through opening 8 to upper compartment 6 and then to atmosphere through vent- 11 thus heating reservoir oil in the upper compartment. Oil feeds through opening 8 to lower compartment 5 as required.

The illustration of our invention shows an internal combustion engine with; airplane propeller, three-way valve and other parts, but we do not limit ourselves to the exact structures or arrangements shown or .described. For example, our invention is also useful with automobile engines and indeed with other power plants in which flow of lubricants at proper temperatures is important. The three-way valve may be controlled manually or thermostatically. We have mentioned water as a desirable heat exchange fluid, but our invention is not limited to water. Many embodiments of our invention are possible without departing from its spirit and substance, which are contained in what we claim as our invention.

We claim 1. In a lubricatingsystem, an oil radiator an outlet below the tubes; a port between the compartment and chamber; and an atmosphere want in the compartment.

3. An oil temperature regulator com rising an oil container foran lnternal com ustion engine system, having a reservoir compartment, a feed chamber with tubes, an inlet into the chamber above the tubes and an outlet below the tubes, a port between the com artment and chamber; and means for con ucting'a heat exchange fluid from the eggine around the tubes.

4. cans for controlling oil temperature in an internal combustion engine, comprising a water radiator and an oil radiator; and a water line from engine to water radiator through oil radiator to engine.

5. Means for controlling oil temperature in an internal combustion engine, comprising a water radiator and an- 011 radiator, one water line from engine to water radiator through oil radiator to engine; another water line from engine through oil radiator to engine; and means for controlling passage of water through said lines.

6. An oil' container for an internal combustion engine s stem, having a reservoir compartment, a eed chamber with tubes, a conical bafile between the compartment and the chamber with port therein, an inlet condult into the chamber above the tubes, an

outlet conduit from the chamber below the tubes, and an atmosphere vent in said compartment.

7. An oil container for an internal combustion engine s stem, having a reservoir compartment, a eed chamber with tubes, a conical bafile between the compartment and the chamber with small port therein, an inlet conduit into the chamber above the tubes,

7 an outlet conduit from the chamber below meavsa the tubes, and an atmosphere vent in said compartment.

8. An oil container for an internal combustion engine, having an upper reservoir compartment containing an atmospheric vent, an intermediate chamber containing an inlet and tubes, communicating means between said compartment and said chamber, and a lower compartment containing an outlet.

9. An oil temperature regulator, comprising an oil container for an internal combustion engine, having an upper reservoir compartment containing an atmospheric vent, an intermediate chamber containing an inlet and tubes, communicating means between said compartment and said chamber, a lower compartment containing an outlet, and means for conducting a heat exchange fluid from the engine around said tubes.

10. In an internal combustion engine sys tem, an engine with water radiator and an oil radlator comprising an upper reservoir compartment containing an atmospheric vent, an intermediate chamber containing an inlet and tubes, communicating means between said compartment and said chamber, and a lower compartment containing an outlet. 11. In combination, an engine with water radiator and oil radiator, one water line from engine to water radiator through oil radiator to engine, another water line from engine through oil radiator to engine, means for controlling passage of water through said lines, saidbil radiator comprising a reservoir compartment, afeed chamber with tubes and inlet into the chamber above the tubes and an outlet below the tubes, and a port between the compartment and chamber. 12. Means for control-ling oil temperature in an internal combustion engine, comprising an oil radiator, one heat-exchange line from engine through oil radiator to the engine, another heat exchange line from engine through oil radiator to engine, and means for controlling passagelof heat exchange fluid through said line's/ GEORGE J.
